Abstract
A light modulation device is disclosed herein. In some embodiments, a light modulation device includes a first polymer film substrate having a first surface and a second surface, an adhesive layer or pressure-sensitive adhesive layer disposed on the first surface of the first polymer film substrate, a second polymer film substrate having a first surface and a second surface, a liquid crystal alignment film disposed on the first surface of the second polymer film substrate, a −C plate; and a light modulation layer containing a liquid crystal compound. The light modulation device has excellent optical properties including transmittance-variable characteristics through characteristic control and proper arrangement of a compensation film, and being applicable to various uses by controlling inclination angle light leakage in a black mode.
